Lesley Evans Ogden's Comment piece opposes a ban on selling shark fin in the US (14 October, p 24). It draws on a paper arguing that this would undermine sustainable shark fisheries. But no shark fishery has ever been shown to be sustainable. The Walt Disney Company found this out at great expense some years ago and finally banned shark fin soup from its menu in Hong Kong (22 July 2005, p 6).
